Edit: nvm, use https://plugins.jetbrains.com/plugin/7127-intellij-plugin-development-with-maven

maven-intellij-project-importer

The plugin enables using Maven projects as IntelliJ plugin project (PLUGIN_MODULE). Raw implementation, based on quick test doesn't work on single-module maven project, the main plugin module has to be submodule otherwise it doesn't pull in maven deps any longer.

Without the plugin:

Plugin projects are normal Java projects, have type JAVA_MODULE in .iml. If one manually edits the type to be PLUGIN_MODULE, on next Maven refresh the change is reverted.

With the plugin:

One has to add Maven property to declare the module to be marked as PLUGIN_MODULE.

<properties>
  <henri5.importer.type>PLUGIN_MODULE</henri5.importer.type>
</properties>

After that, just do Maven refresh. It's not smart though - don't try adding ANDROID_MODULE or something else there. For there needs to be different custom importer. Make a pull request or whatever.

If plugin doesn't seem active during startup from IntelliJ, open module settings -> plugin deployment and edit META-INF location forth and back so that .iml file will get a line about plugin.xml location.
